Re: [xml-dev] ANN: a portable data component -- length

I notice that last link - the semantic web OWL rendering - is version 0.1
so just at a kind of proof of concept stage but I notice too it has a creative
commons licence so maybe you could use it with some XSLT to convert the
codes into a genericode codelist for the SI codes.
